…aft module) Otto-268 backfill: drain-log for PR #206 covering 22 threads — the densest single-PR drain in this session, including 6 mathematical- correctness fixes (K-relations retraction precision, GKT homomorphism scope, probabilistic-vs-possibilistic, lineage multiplication semantics, N[X] retraction, Tropical R=ℝ-vs-ℤ implementation). Per Otto-250 training-signal discipline. Pattern observations capture four load-bearing patterns: 1. K-relations + GKT homomorphism precision fixes share shape: subset-vs-superset framing errors that Codex catches reliably across math docs. 2. Stale-resolved-by-reality at ~23% (`||` table prefixes pinned to pre-fix revision). 3. Implementation-vs-math-definition tension: Tropical math is ℝ; Zeta's pin is ℤ (int64 for grid-cost / shortest-path). 4. Cross-reference column-name accuracy as its own findings class (TECH-RADAR "11" in Round column not Ring column).

This thread ID is already used in A1 for a different finding, so the log currently contains only 21 unique IDs despite stating there were 22 unresolved threads. Reusing one ID for two unrelated findings makes one real review thread untraceable and weakens the "preserved verbatim" record this drain log is intended to provide.

Pull request overview
Adds a PR-preservation drain log for PR #206 (craft semiring-basics module), intended to archive review threads, responses, and resolutions per the repo’s PR-preservation discipline.
Changes:
- Introduces
docs/pr-preservation/206-drain-log.mddocumenting the drain of 22 review threads from PR #206. - Records outcome classes (FIX / STALE-RESOLVED-BY-REALITY / DEFERRED) and summarizes the underlying math/format findings.
